      I’ve put pex as shower head supply from the shower/tub valve. But now I’m wondering if there would be a noticeable reduction in water pressure over copper because of the differences in inner diameter. What do you think?

      Hey Doug

      I install shower supplies with pex all the time and have never seen a  difference in pressure. Thats probably because most shower heads are restricted to at least 2.5 gallons of water per minute. 1/2″ pex would most likely be pumping out 7-8 gallons per minute unrestriced

      IF you plan to add multiple body sprays, that might be an area where you want to bump up to 3/4″ pex so that the fittings are 1/2″,  or go copper all the way around

      Hope this helps
